The standard cabinet is supplied with the earth/connector plate, with attached
RF cables, located on the right side of the top section. If required, an optional
earth/connector plate can be fitted on the left side of the top section instead.
Figure 3-11 shows the layout of the right earth/connector plate viewed from
inside the top section (the layout for the left plate is a mirror image of this). The

cables to earth
plates
When installing a multiple cabinet configuration or expanding an existing site it
may be necessary to fit long RF cables to an existing earth plate. Extension RF
cables are listed in Table 3-4 in this chapter.
To fit extension RF cables to an earth plate:
1.
Remove the grey weather seal from an unused RF position, on the earth
plate and discard.
2.
Remove the nut and washer from the fixed bulkhead connector of the
extetsion RF cable.
3.
Feed the threaded portion of the bulkhead connector through the earth
plate from the inside.
4.
Refit the washer and nut to the bulkhead connector and tighten to the
correct torque, (see Site requirements and considerations in Chapter 2
of this category).
